On our present trip my walking mate and I stopped to examine a hemlock trunk, the bark of which a woodpecker of some kind, almost certainly a sapsucker, had riddled with holes till it looked like a nutmeg grater; and the most noticeable thing about it was that the punctures--past counting--were all on the south side of the tree, where the sap may be presumed to run earliest and most freely. Why this particular tree was chosen and the others left is a different question, to which I attempt no answer, though I have little doubt that the maker of the holes could have given one. To vary a half-true Bible text, “All the labor of a woodpecker is for his mouth;” and labor so prolonged as that which had been expended upon this hemlock was very unlikely to have been laid out without a reason. Every judge of rum cherries knows that some trees bear incomparably better fruit than others growing close beside them; and why should a woodpecker, a specialist of specialists, be less intelligent touching hemlock trees and the varying quality of their juices? A creature who is beholden to nobody from the time he is three weeks old is not to be looked down upon by beings who live, half of them, in danger of starvation or the poorhouse. The end of summer is the top of the year with the birds. Their numbers are then at the full. After that, for six months and more, the tide ebbs. Winter and the long migratory journeys waste them like the plagues of Egypt. Not more than half of all that start southward ever live to come back again. Of this every bird-lover takes sorrowful account. It is part of his autumnal feeling. If he sees a flock of bobolinks or of red-winged blackbirds, he thinks of the Southern rice fields, where myriads of both species--“rice-birds,” one as much as the other--will be shot without mercy. A sky full of swallows calls up a picture of thousands lying dead at once, in Florida or elsewhere, after a winter storm. A September humming-bird leaves him wondering over its approaching flight to Central America or to Cuba. Will the tiny thing ever accomplish that amazing passage and find its way home again to New England? Perhaps it will; but more likely not. For the present, nevertheless, the birds are all in high spirits, warbling, twittering, feeding, chasing each other playfully about, as if life were nothing but holiday. Little they know of the future. And almost as little know we. Blessed ignorance! It gives us all, birds and men alike, many a good hour. If my playmate of long ago had foreseen that he was to die at twenty, he would never have been the happy boy that I remember. Those few bright years he had, though he had no more. So much was saved from the wreck.
